DEMO MANUAL DC2293A
LTC2933
Programming Board for Programmable Hex
Voltage Supervisor with EEPROM
Description
The DC2293A programming board contains the circuitry
needed to program and verify the EEPROM of the LTC2933.
This is its sole purpose. The LTC®2933 comes in either a
16-pin SSOP or a 16-pin DFN package. The DC2293A-A
supports the SSOP and the DC2293A-B supports the
DFN package.
The LTpowerPlay GUI stores configuration settings into
the LTC2933 EEPROM. Download and install the software

LTpowerPlay GUI Software
LTpowerPlay is a powerful Windows-based development
environment that supports Linear Technology Power
System Management ICs with EEPROM, including the
LTC2933 Programmable Hex Voltage Supervisor. The
software supports a variety of different tasks. You can use
LTpowerPlay to evaluate Linear Technology ICs by connecting to a demo board system. LTpowerPlay features an
offline mode to build a multi-chip configuration file for later
use with hardware. LTpowerPlay provides unprecedented
system level diagnostic and debug features. It becomes a
valuable diagnostic tool during board bring-up to program
or tweak the power management scheme in a system or
SYSTEM TREE OF
ALL DEVICES
CONFIGURATION SETTING FOR
ALL DEVICES IN SYSTEM TREE
to diagnose power issues when bringing up rails. LTpowerPlay utilizes the DC1613 I2C/SMBus/PMBus Controller
to communicate with one of many potential targets, including the DC2293A demo system or a customer board.
The software also provides an automatic update feature
to keep the software current with the latest set of device
drivers and documentation. Download the software from:

DEMO MANUAL DC2293A
Quick Start Procedure
The DC2293A programming board makes it easy to program and verify the LTC2933 EEPROM contents.
1. Place jumpers and switches in the following default
positions:
ASEL0: L
OFF
S1:
3. If using DC2293A-A, open the pinch contacts of the
socket by pressing down and holding the top of the
spring loaded socket frame. Place the IC inside the
socket with pin 1 located in the upper left corner. Slowly
release the top of socket frame, allowing contacts to
pinch together and grip IC leads. See Figure 5.
NOTE: By default, the ASEL0 jumper is set to low. If you
wish to program a device with an address other than
0x1C, adjust the ASEL0 jumper appropriately. Consult
device data sheet for details.
2. Connect the DC1613 USB controller to your PC. Plug
the ribbon cable into connector J1 of the DC2293A
programming board. See Figure 4.
Figure 5. DC2293A-A and IC Installed
Figure 4. DC2293A-A with Open Socket
NOTE: Removal and insertion of the IC should be done
with either tweezers or a vacuum device, and also with
the power switch S1 set to OFF.

Quick Start Procedure
4. If using DC2293A-B, flip open the socket lid and place
the IC inside with pin 1 located in the upper left corner.
See Figure 6.
PIN 1 INDICATOR
5. Set the power switch S1 to the ON position. The VDD33
LED will illuminate, indicating the on-chip regulator is
providing internal power. If the LED does not illuminate,
check the orientation of the IC in the socket. Pin 1 must
be in the upper left corner.
6. Launch the LTpowerPlay software from your PC. The
device programming utility shown in Figure 8 should
pop up automatically. If it does not, then select the
Utilities>Programming Utility from the menu shown
in Figure 9.
7. Click “…” next to the selection box and select a .proj file
from your system to program the device. See Figure 8.

Quick Start Procedure
8. Click the “Program and Verify” button (See Figure 10)
and wait for the process to complete. After the process
is complete, you will see “Successfully Programmed
and Verified Device” in the status bar at the bottom.
See Figure 11.
